Having won the Inspiration in Control Award twice this year (CVR and SAC), you can imagine we are always looking for "better" ways to control our robots.
Our Cypress board never worked this year, so we are currently looking for a reliable alternative as well.
The Teensy as a HID has been posted here on CD a few times. The emphasis is always on the "I" part of "HID". In other words, an Input device to the DS.

A quick overview of the site linked supports the Input option(s), but the question remains, can it also handle "Output"? Even something as simple as driving an LED or two?

[EDIT]
On a deeper dive into the Teensy link, I believe I found the answer. YES!!
